The computer is too laggy to detect viruses, but it is found that the memory is very high in the house. What's the matter? Now I'll teach you how to reduce physical memory Hope to help you!
Solutions to excessive physical memory occupation of notebook computers
Start "Windows Task Manager", press the shortcut key "Alt + Ctrl + delete" and click the "performance" tab to check the usage of system memory and physical memory
Click the start menu, and then enter the msconfig command
The "system configuration" dialog box will pop up, and then select the "service" tab You can see many running services Check the front check box Then click the "disable all" button OK (when disabling services, first determine the services that are not necessary for the system (that is, disabling them will not affect the operation of the system)

1. Generally, more than 80% of computer system faults are software faults. At the same time, most software faults are relatively easy to deal with, while most hardware faults are caused by peripherals. Therefore, the analysis and fault finding should be carried out in the order of "software before hardware, external before internal".
2. Common software faults.
A. error prompt: in case of software failure, many errors can be captured by the application software or operating system and give corresponding prompts. Such failures are generally caused by software defects, software conflicts, improper configuration or wrong operation.
B. application software fails to start normally: such failures are generally caused by software conflict, wrong operation, improper configuration or virus.
3. Handling methods of common software faults.
A. use anti-virus software: in case of inexplicable slow down or error of the system or application, scan the whole system with anti-virus software to determine whether the system is poisoned.
B. single application system failure: for single application system failure, the application is generally reinstalled. If you are familiar with the system, you can check the system configuration first and then decide whether to reinstall the system
4. Causes and treatment methods of common hardware faults.
The causes of computer hardware failure are mainly related to the use environment, users' operation habits, natural aging of hardware and poor quality of hardware products. Under normal circumstances, the hardware failure of the system can be eliminated as long as the faulty hardware equipment is found and replaced.
5. When the computer system has a fault, first confirm the fault phenomenon through observation and inspection, then analyze the fault phenomenon, judge the possible cause of the fault of the computer system according to the corresponding relationship between these fault phenomena and possible causes, and then use the troubleshooting method to eliminate the impossible fault causes, so as to gradually determine the fault causes. When the fault causes are determined, Then start the maintenance.
6. The above contents involve relevant computer knowledge. If non professionals suggest to find enough experience before actual operation, some complex computer faults need to be repaired by professional maintenance points and professional maintenance personnel.
